From MMA Junkie:
"I would have to say that our school was really ahead of the curve," Nelson said. "We started training mixed martial arts in, well, it was 1992, but even before I had my own school we were already mixing Thai-boxing and shootwrestling, and I wrestled for the University of Minnesota. We just always had been putting stuff together and combining. That's kind of how I did things.
"We've had a really good training camp, a lot of guys in there," Nelson said. "This has been an extremely good camp because we've had a lot of guys that are big and can move. We brought in a guy from Arizona who was an all-armed forces boxing champion who is 300 pounds and can hit like a Mac truck."
"Brock is a very smart fighter," Nelson said. "Since his first fight, he went in there and that was more just pure get-in-there, raw aggression, try to run them over like a truck. You could see from that fight to Heath Herring to then with Randy Couture, you see a steady growth in his striking development and ability to pace himself – control to not be so anxious in the ring.
"He's got the ability to really run through you like a freight train, ... but at the same time he now has a lot more movement."
They brought in 7 time world jiu jitsu champ Rodrigo "Comprido" Medeiros to train Lesnar before the Heath Herring fight, but I haven't heard who they've brought in for this camp.
